Hey Steve,
No problem.
The 1.1b3 installer from the Novation beta site is actually only for the Launch Control (not the XL) so that’s why it won’t work. If you have tried to send the 1.1b3 file to LCXL I suppose that could cause a problem although I cannot say for sure. I would recommend re-updating LCXL with the correct 1.2 updater from novationmusic.com (running this installer will also verify if the version is still at version 59 - which is correct and also working fine here).
I’ve checked out on the Bomebox MIDI router page too and I’m seeing ‘USB 1 Launch Control XL [1]’ and ‘USB Launch Control XL [2]’ in all my relevant slots but I’m not seeing LC 1,2 or USB LC etc. at all. ‘LC’ would suggest a Launch Control rather than Launch Control XL too. I maybe mistaken but I believe both the Launch Control products have a couple of USB IDs which are set-up to be; the Script templates ID (for Ableton etc), the HUI control ID and the MIDI controller ID. But the Bomebox is a very comprehensive MIDI utility so these different IDs should not have any detrimental effect. Although I have no idea about the ‘pending’ stuff… sorry.
You mentioned a different power source in your response… and say it has made a difference with the LEDs what was that difference? are the LEDs staying on now?
Another thing you could try is reseting the Bomebox back to factory default and if needed maybe updating the firmware on it too, I think you may need to contact Bomes to get that though. The Factory default routings should connect the USB MIDI to the DINs automatically.
If you are still struggling PM me and we can try to sort it that way.
Fingers Crossed!
